3 Claims.

This invention relates to cooking ranges and particularly toelectrically heated ranges.

It is an object of this invention to provide convenient means for theillumination, of the range.

a It is afurther object of this invention to locate the indicating andcontrol devices near together and to provide for their illumination bylamps conveniently located with respect to the grouped devices.

0 It is a further object of this invention provide a rotatable supportfor each lamp whereby the lamps may be individually moved in position toilluminate the control devices or to illuminate the part ,of the stovewhich is being used.

6 The invention also contemplates a clock mounted at the upper part ofthe range and I strongly illuminated by said lamps when they are in theposition in which they are normally kept.

The invention also contemplates a range in E0 which the top is dividedinto a cooking area equipped with heaters and a working area free fromheaters. It is an obiectof said invention to provide for the selectiveillumination of one part of the top or the other.

It is also an object of this invention to provide for generalillumination of the kitchen from the lamps when in appropriate position.

Other objects of the invention and details of construction will beapparent from the following 30 description and the accompanyingdrawings, in which:

Figure l is a front elevational view of the range equipped with itslamps,

Fig. 2- is a side elevational view of the same,

35 Fig. 3 is a plan .view'showing the lamps in their normal position,

Fig. 4 is a plan view showing the lamps in a rotated position,

- Fig. 5 is a front elevational view of one lamp 40 and its support,

lgig. 6 is an end elevational view of the same, an

Fig. 'l is adetailed view showing the method of securing the lampsupport to the range. j 45 The range l is of cabinet form and consistsof a cabinet proper having a top 2 and a backsplasher 3 projecting fromthe rear edge of the top in a familiar way. The back-splasher comprisesa front wall 4 and a top 5. The front wall 59 is bent toward the back ateach end forming closures for the end. The back-splasher is thus ineffect a hollowstructiu'e although if desired'it may be open on the sidethat is toward the wall of the kitchen. 55 Various devices forcontrolling, indicating or otherwise facilitating the use of the rangeare gathered together in the back-splasher. As

whether the oven heaters are working and devices to show the temperaturein the oven, etc. One such temperature indicating device is shown at 9."These devices either project through openings in the front wall orilluminate windows therein.

Device are provided in the back-splasher through which the time at whichheat will be turned off is controlled. Indicators of such time areprovided, preferably, adjacent the face of a time clock It) mounted onthe top of the back- 16 splasher. The usual ovens and warming closetsare provided in the body of the cabinet. The top 2 of the cabinet has aspace l2 free from heating plates which is for the operator to use as atable. The other part of the top surface 2 is provided 2( with heatingplates l4, which the operator may,- usefor cooking. 1

On each side of the center of the back-splasher an illumination deviceI5 is mounted. The following description of one of said illuminationdevices applies equally to each of them. Preferably it consists of ashade l6 covering a lamp l1 (Figs. 5 and 6) which is mounted in a lampsocket l8 and controlled by a pull chain IS. The I shade I6 is open atthe bottom, as indicated by v 'the dotted lines, showing the thicknessof the side and end walls. An additional opening is shown at'-22. It islocated in that end wall of the shade which is most remote from thetubular shaft 23 upon which the shade issupported. The shade is securedto this shaft, as indicated at 25. Be-

tween the shaft proper and the portion to which theshade is, attached aright-angle bend 26 is provided so that the long dimension of the shadeis horizontal although the shaft is vertical. 4o

Wires 28 extend through the shaft from any suitable power connection tothe lamp l1 and to a socket 21 which forms one member of a separableconnection. The second member of this separable connection is not shown.It is intended -to secure a cord to the socket 21, which cord can passover the back-splasher to the space between the range and the kitchenwall and extend to any device which it is desired to furnish with power,such as a toaster or percolator. Wires from the socket 21 extend througha tube 29 which forms a continuation of the shaft 23. At one point wiresbranch from this tube and are connected to the lamp socket l8.

In the back-splasher brackets are provided,

which are secured to the top wall of the backsplasher, preferably byspot welding flanges 3| which are a part of the bracket. The flanges 3|are united by a U-shaped member which is the' bracket proper. The bottomof the U-shaped member has a hole 33 for the reception of a tube 35. Thelower end of this tube is provided with a flange 31 by which it issecured to the bracket in any suitable manner, preferably by bolts 38.The tube is thus secured in an upstanding position. Its upper end isabove the top wall of the back-splasher which is provided with a holefor the combination of the tube.

The tube is of suitable diameter to receive the end of the shaft 23.This shaft is equipped with a pin 38 secured therein in any desiredmanner,

preferably by providing the wall of the shaft 23 with two diametricallyopposite holes through one of which the pin 39 projects and through theother of which a reduced end of the pin, as shown at 40, extends. Theexterior end of the end of the reduced part 40 is expanded, by spinningor in any other desirable way, to secure the pin 39 in the shaft 23.

pin 39 passes through the open end 4| of a T- shaped slot, the bottom ofthe stem of the T being at the top of the tube. The cross part of the T*constitutes a horizontal portion 42 of the slot.

The pin 39 passes through the vertical portion 4! of the slot and isreceived in the horizontal part 42. The shaft 38 is'then rotated untilthe pin contacts one end of the horizontal portion 42 of the slot. Thisbrings the illumination device I5 carried by the shaft into the positionillustrated in Fig. 3. This is the position normally occupied by thedevice before the operator rotates it.

In this position, light from the lamp II passes through the end of slot22 and illuminates the face of the clock Hi. There being two of theillumination devices, the clock I0 is illuminated from both sides andlight is reflected therefrom in all directions so that the clock iseasily read from any part of the kitchen. In this position of theilluminating device, the bottom of the shade l6 permits light from thelamp II to descend upon the front wall 4 of the back-splasher 3. Thedevices projecting through the wall 4 are thus well illuminated.

When the range is being used as a table, the left-hand device l5illuminates the work space II. The operator may, therefore, move thelefthand device l5 into the position illustrated in Fig. 4 forconvenience in working on the table. If the operator is cooking anything,on the top of the range, the right-hand device l5 may be swung in theposition illustrated in Fig. 4 for convenient inspection of the contentsof the cooking vessels. If desired, both lamps may be rotated asillustrated in Fig. 4, thus illuminating both the table surfaces and thecooking surface. When the illumination of the top of the range is notneeded, the lamps may be moved into the position shown in Fig. 3 wherethey illuminate the clock and the kitchen generally.

When the shaft is entered into the tube 35, the

When it is desired to use a percolator, a. toaster or other auxiliaryheat device, the cord from such device may be connected to a plug andthe plug inserted into the socket 21. This connection may be made in anyposition of the shaft 23 and the cord will extend over the back-splasherand down behind it and to the auxiliary device located in any convenientplace. If, afterward the lamp fixture I5 is moved forward the cord willbe dragged over the back-splasher and will connect to the socket 21 inany position of the fixture ii. If the fixture is pushed back toward thebacksplasher the cord will be dragged down by the weight of the partbehind the back-splasher and will slide over the top edge thereof as thelamp fixture approaches. Thus the cord is not in the way at any timealthough energized by permanent connection 28 within the fixture.

Many modifications will occur to those skilled in the art and we do notdesire to be restricted intentional limitations are stated in theclaims.
